Abstract: Aiming at the problem that the current resource scheduling algorithm could not meet the requirements of business diversification, we proposed a cloud computing resource scheduling algorithm based on unified deployment and business management. Firstly, business was classified and unified management according to business change in real time to adjust resource requirements. Secondly, transformation between soft constraints and hard constraints of business was used to adapt to requirements of business diversification. Finally, the validity and superiority of the algorithm was tested by simulation experiment. The experimental results show that compared with other algorithms, the proposed algorithm can greatly improve utilization rate of cloud computing system resources, and  meet the requirements of practical applications.
